Property Taxes

Property taxes become due and payable each year when the current year tax roll is completed by the County Treasurer. Property tax statements are mailed out around mid-February.  If you have not received your statement by March 1st  please email or call our office.
 

Due Dates:

  • First half property tax payments must be paid or postmarked by April 30.
  • Second-half payments must be paid or postmarked by October 31
  • Interest and penalty on delinquent accounts will be charged as outlined in RCW 84.56.020.

Change of Address:

If you need to update your mailing address, write the correct address on the back of your payment coupon when submitting your payment. Or send an email to Treasurer@co.chelan.wa.us with your property ID number and new mailing address.

 

Understanding Property Taxes:
Property tax is the oldest tax levied in the state of Washington, and it’s also one of the more difficult to understand. Property taxes are essential for funding local services such as fire protection, libraries, parks and recreation, and public schools.  This short video explains the basics of property taxes.
